Abstract

Platinum-based nanoparticles decorated on carbon supports (Pt/C) are widely used as electrocatalysts in polymer electrolyte fuel cells (PEFCs). Meanwhile, SnO2 is more stable than carbon at high potentials in cathodic environments. Highly durable Pt/SnO2/C electrocatalysts have therefore previously been developed using carbon nanomaterials as an electron-conducting backbone and SnO2 as a stable support layer for highly dispersed platinum nanoparticles. Here, we report on the development of Pt/SnO2/C electrocatalysts based on mesoporous carbon (MC) scaffolds. The electron conduction pathway through SnO2 was minimized by reducing the SnO2 loading. The use of Pt/SnO2/MC electrocatalysts resulted in high activity towards the oxygen reduction reaction (ORR) as well as excellent start-stop voltage cycling durability in half-cell conditions.
